\ Ventilating Apparatus for Passenger-Cars, of

, object the provision of means for facilitating parts.

which the following is a specification, reference being hadtherein to the accompanying drawing. J

' This invention relates to an improvement in car ventilating apparatus, and has for its the ventilation of a car, by means of afan inclosed in a pecilliarly constructed and supporting casing; the fan being driven through the medium of a traction wheel.

With this and other objects in view, the

invention consists of certain novel construc tions, combinations, and arrangements of parts, as will be hereinafter fullydescribed and claimed. 7

In the drawings: Figure l is a vertical, sectional view of the fan-casing, and showing in side elevation, the fan and its cooperating Fi 2 is a transverse, sectional view of the car aving'attached theretUan a'pparatus constructed in accordance with the present invention. Fig. 3 is a sectional-view taken on line 3, 3, Fig. 1,-and looking in the direction of the arrow. Fig; 4 is a vertical, sectional view taken on line 4,4, Fig. 1 Fig. 5 is a longitudinal, sectional view of a car body and showing 'our ventilatin apparatus attached thereto. Fi 6 is'ap an view of J the device for a plura ty of cars or coaches,

and 4. The bracket is securedto the floor 1,

showing the fan-casing, friction-wheel, and shaft. Fig. 7 is a fragmentary, sectional view of the devioe.

Referring to the drawings by numerals, 1 designates the floor of an ordinary car or vehicle body, to which floor is secured an inverted substantially U-shaped bracket, which comprises a top portion 2 and side portions 3 by any suitable fastening means, as for in-' stance, bolts 5,5,: The slde 3 of the bracket is provided at its lower end with a bifurcated portion, which terminates in depending arms 3 and 3 the arm 3 being provided with'a bearing 3, while the arm 3 is provided with a bear ng 3 Journaled in the bearings-3 and 3 is a transverse shaft 3;", which is detachably secured in said bearing, by reason of the fact that the section '3" is detachably secured to the arm 3 by any suitable fastening means, as for instance, bolts 3 The which shaft 10 is journa'led. As the fancastirely upon shaft 10, the same is bodily lifted, when shaft 10 is lifted. It will be noted that owing'to the lifting of shaft 10, the transverse shaft or pivotal bearing 3 has. a sli ht rotary movement upon the bifurcated on of side 3. Furthermore, the pivotal bearing 3 can be quickly detached by removing the bolts 3 and section 3 A friction-roller or wheel 15 is fixedly secured to shaft .10, and is adapted to engage the periphery 'of a traction-Wheel 16. The traction-wheels 16 are secured to the axles 17, which-support the car-body.

The side 4 of the primary bracket is provided, at its lower end, with a bifurcated portion, within which is slidably mounted a earing composed of a pair of sections 18. The shaft 10 is journaled in this sectional bearing, and the sections are secured together, by any suitable fastening means, as

or instance, screws .or threaded bolts 19. A yieldable member, preferably, a coil spring 20,- has its upper end seated within a socket 21 of-the side 4, and the lower end of said spring 20 is seated in a socket 22, Fig. 3, of t eulpper section of the bearing. The sectlona eari within the bi rcated portibn of the side 4, so that when the operator grasps the ring 23, attached to the upper end .of chain 24, and

slightly lifted for removing the frictionwheel or roller 15 off of the traction-wheel 16. The chain24 is secured to a hook 24, ,which hook is fastened to one of the sections 18. However, immediately upon the operator. releasing ring 23, the spring 20 and the weight of the fan-casing will force the friction-roller 15' against,

wheel, and if the car is in motion, the fan will be operated. The downward, slidin movement of the sectional bearin 18- Wil be limited by means of a 'detacha 1e plate or bar 18 provided thefritztiOn-wheel '15 wheel 16. V I

s vItwill be obvious that'owing to the jourshaft 3 is provided with a central bearing in is slidably mountedor guided pulls upwardly thereon, the shaft 10 will be rialing of shaft 10 in the. pivotal bearing 18,

ing, hereinafter described, is supported en does not come in contact with a. tractionpreferably, the periphery of the tractioh- T closed position.

within the side 3, a slight pivotal movement of the shaft 10 will, be permitted,and as the sectional bearin carried by the bifurcated end of side 4 wil also permit the shaft 10 to have a vertical movement, the movement of the shaft is sufficient for removing the friction-wheel or roller from the tractlon-wheel.

When it is desired to lift the fan, to prevent-it from rotating within the casing 11, this may be accomplished by passin a chain over the notched standard 25, and t e chain will be securely fastened, thereby retaining the shaft 10 in a raised position. It will be noted that we have provided means for elevating the shaft 10, and also looking or fastening means for, retaining the shaft and the friction-wheel in an elevatedor inoperative osition. 4

If t e fan-casing is inclosed entirely by a structure, air may be supplied to the fan-casing, through the mediumof ipe 26, which pipe 26 is provided with, preferably, a flexible, valved tubing 27 hereinafter described.

Secured at one end to the upper portion of the casing 11, and slidable in 1ts bracket, is a stem 29, to which stem is secured a valve 30, and interposed between the stem 29 and valve 30, is yieldable means, as for instance,

a coil spring-which normally exerts pressure upon the valve 30, for holding tlie same in a The tension of thes ring is such as to permit the valve 30 to be ift'ed when the pressure in the casing 11 becomes too great. i

The casing 11 may be provided with one or more side-openings or apertures 31, where- I pipe 35 is by a plurality of cars may be attached by tubings to the fan-casing, so that said cars may be ventilated by supplying air from the fan-casing to the same. 1

The fan-casing is provided, preferably,

at its top with a cylindrical extension 32, upon which is mounted a flexible tubing 33, whereby the casing is laced in communication with a horizonta pipe 34. The pipe 34 may be connected to another pipe. 35, by means of a flexible coupling 36. Each rovided with an ordinary constructed va ve 37, by --means of which the .flow of compressed air through the same, is

controlled. Communicating with the horizontal pipes 34 and 35 are laterally-extending or auxiliary pipes 38. Secured to the outer endsofeach'one of the auxiliary pipes 38, is

a vertical pipe 39. The pipe 39 is, prefer ably, positioned contiguous to the side of the car body, arid terminates atits upper end in a substantially horizontal extension 40, extending toward the-center of the car.

The extension 40 is provided at its upper or outer end with anjapertured tube or pipe 41, which is constructed for permitting compressed air to be discharged into the compartment or car. Each pipe 39 is, referably, proyided with an ordinary va ve, at

42, whereby the amount of air passing through i of the connected cars or reat, the relief va ve 30 will be actuated or relieving the casing and pipes or tubings of the extra strain. The assage of air in any one of the pipes or tubings is controlled by valve means, and if itis desired, the discharge of air through any one of the sprayers 41, may be prevented, while the dischar e of air through the other sprayer or sprayers is permitted.

The tubing 27 is, preferably, extended into the car beneath one of the seats 43. The inner or upper end 44 of the tubing 27 is provided with an inlet port or opening 45, Fig.

7, which is normally closed by a springpressed valve 46 similarly constructed to valve 30. The valve 46 is positioned in the tubing 27 and adapted to permit air to be sucked in and su plied to the valve casing 11. By reason of t is valved structure of the outer or upper end of tubing 27, atmosphere is drawn into the fan-casing 11 from the bottom of the car, and as the air is discharged downward from the top of the car, it will be noted that there is a current or circulation created throughout the entire car.

. Supported by any suitable means, as for instance, bracket 47, contiguous to 'theport 46, is a cup or receptacle 48, within which I liquid or any compound may be placed, thev odor of which wil commingle w1th the air passingthrough the port 45- into the tubing 27, and which odor will subsequently pass throughthe sprayers 41.iI1,to.-the car.

It is. to be noted that we have provideda tilting shaft; which is capable of being swufng' upward at one end for p acing the fan outof operation, and, furthermore, we have provided a casing adapted to be tilted, whereb whensaid casing is'tilted, the fan therein wi l he placed out of operation. The tiltingof the casing necessitates the flexible connection or tubin pipes 34, as Wlll be obvious upon considering V 33 between the car or trainthe foregoing description.
